I tracked the movement of water molecules around residues 65 to 67 of my protein (GFP crystal structure) .. According to the literature water should not enter the protein (reason being the cage like structure of GFP) .. but in VMD, 2 water molecules have been tracked to interact with chromophore ... So , I am a bit confused as it should not have happened ?? ... For my analysis I need to check whether the water is entering the protein or not .. Since I have simulated some variant structures (long loops) of GFP and I need to check how this structure would or would not lead to the entrance of water ??<br>

<div>Hi,<div><br></div><div>I am completed a 3 ns simulation of a 230 aa protein .. Now I want to check whether the water is entering the proteins and through which side of the protein .. Since the whole protein is surrounded by water I don't know how this can be done .. is there any command to check .. also I have tried doing it in VMD but there I am not able to do so ??</div>
